The main objective of this project proposal is to move away from trial and error approach and go more in deep in the knowledge of the fundamentals of this technology and to reach an exhaustive and multi-scale knowledge about deep cryogenic treatment and its effects on materials including micro-structural mechanisms and related changes in macroscopic properties. Improved fundamental knowledge is essential in order to prepare clear guidelines as known in conventional heat treatment technologies and to develop more robust and standardized cryogenic processes, which would lead to more predictable results when they are used in industry, including large and heavy equipment. Challenge of the proposed research is to provide a more reliable approach and a more in-depth understanding of the correlations between microstructural changes and properties by overcoming the current trial-and-error approach. In this way new possibilities in terms of further material properties improvement can be expected, not being limited only to steel but also to other metals.
